Wide Aperture Exoplanet Telescope: a low-cost flat configuration for a 100+ meter ground based telescope [PDF]
arXiv, 2018 The Wide Aperture Exoplanet Telescope (WAET) is a ground-based optical telescope layout in which one dimension of a filled aperture can be made very, very large (beyond 100 m) at low cost and complexity. With an unusual beam path but an otherwise-conventional optics, we obtain a fully-steerable telescope on a low-rise mount with a fixed gravity vector ...

Angewandte Chemie International Edition, EarlyView.Photoredox autocatalysis is revealed to access cyclic biaryl sulfonamides (BASNs) without an initial exogenous photocatalyst. While unveiling photoredox autocatalysis is important to the enrichment of basic research, this has also led to further practical applications such as rapid discovery of novel, potent and readily accessible photocatalyst ...

International Journal of Satellite Communications and Networking, EarlyView., 2023 The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

Monte Carlo comparison of medium-size telescope designs for the Cherenkov Telescope Array [PDF]
arXiv, 2013 The Cherenkov Telescope Array (CTA) is a future very high energy gamma-ray observatory. CTA will be comprised of small-,medium- and large-size telescopes covering an energy range from tens of GeV to hundreds of TeV and will surpass existing telescopes in sensitivity by an order of magnitude.

LIGHT ABERRATION IN OPTICAL ANISOTROPIC SINGLE-AXIS MEDIUM
East European Journal of Physics, 2017 The entrainment of the light flux by a uniaxial anisotropic medium and its influence on the measurement of stellar aberration are analyzed. The influence of the entrainment of the light flux by an isotropic medium on the measurement of stellar aberration

Large Size Telescope camera support structures for the Cherenkov Telescope Array
, 2013 The design of the camera support structures for the Cherenkov Telescope Array (CTA) Large Size Telescopes (LSTs) is based on an elliptical arch geometry reinforced along its orthogonal projection by two symmetric sets of stabilizing ropes.

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?
The Anatomical Record, EarlyView.Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...
